The Anatomy of Lamina Pretrachealis Fasciae Cervicalis

Abstract

Summary: The definitions concerning the fascia pretrachealis is either contradictory or insufficient in anatomy textbooks. The fascia pretrachealis is clinically important in the procedure of tracheostomy, mediastinascopy and also in tracheal and bronchial trauma. The anatomy of the fascia pretrachealis (extension, relation and the attachments) was reexamined using cadaveric preparations and the clinical value of the fascia is reinforced. The fascia pretrachealis is attached to the upper brim and to the oblique line of the thyroid cartilage and continued its course on the anterior surface of the trachea and fused with the advantitia of arch of the aorta, posterior aspect of pulmonary artery and the pericardium.Laterally it is attached to the cartilagenous part of the trachea. Also contraversial literature concerning description of the fascia pretrachealis has been evaluated.

Chest pain in patients with COPD: the fascia’s subtle silence

“… 65 The pretracheal fascia, deriving from the deep fascia of the neck, originates from the upper boundary of the thyroid cartilage, then covers the trachea anteriorly, touches the posterior part of the parietal pericardium (the fascia that envelopes the heart) and joins the endothoracic fascia covering the diaphragm. 66 It is probably innervated by the recurrent laryngeal nerve. 66 The parietal pericardium is a connective structure; it is the fascial system that covers the pericardial sac, connecting the heart and the abovementioned structures with the diaphragm, the sternum, some ribs (from the fourth to the sixth one on the left) and the thoracic vertebrae (D10–D11).…”
